Abstract: A buffer assembly for a noble gas isotope analysis device, including an air inlet pipe and an air-pressure buffer member. The air inlet pipe is connected to the noble gas isotope analysis device, and is provided with a valve. The air-pressure buffer member is provided in the air inlet pipe, and includes a connecting pipe arranged inside the air inlet pipe. Multiple pneumatic components are sleeved outside the connecting pipe, and are configured to be deformed under the action of a gas flow to decelerate the gas flow. A noble gas isotope analysis device including the buffer assembly and an isotope analysis method using the noble gas isotope analysis device are also provided.
